Performance of Rabi Blackgram (Vigna mungoL.,) under Different Sowing Windows

Field experiment was conducted at the College Farm, Agricultural College, Mahanandi of Acharya N.G. Ranga Agricultural University during the period from October, 2017 to January 2018 to evaluate the performance of rabiblackgram (Vigna mungo L.) under different sowing windows. The experimental site was sandy loam and it was neutral in reaction with a pH of 7.30, EC of 0.20 ds m-1. The experiment comprised four blackgram varieties viz., TBG-104, LBG-787, GBG-1 and PU-31 and four sowing dates viz., 1st fort night of October, 2nd fort night of October, 1st fort night November and 2nd fort night November.The experiment was laid out in randomized block design with factorial concept (FRBD) having sixteen treatments and three replications. Results showed that varieties and dates of sowings significantly influenced all the parameters in the growth attributing experimentation characters such as plant height, dry weight, leaf area index, and yield attributing characters like number of pods plant-1, number of seeds pod-1 and 1000 seed weight and seed yield (kg ha-1), haulm yield (kg ha-1) and harvest index (%) and were found highest in PU-31and lowest in LBG-787. With regard to sowing windows, the higher as well as lower values of these parameters were observed with sowing 1st fort night of October and 2nd fort night of November, respectively. Sowing PU-31 on 1st fort night of October and 2nd fort night of November gave the highest seed yield (856.42 kg ha-1) and haulm yield (2473.96 kg ha-1) respectively. Overall the results proved that 1st FN of October seems to be the appropriate sowing date for getting higher yield of black gram during rabi season. Among different varieties PU-31 came out with higher yield followed by GBG-1, TBG-104 and LBG-787.
